Problem Finding/Effects and their causes

Most events—called “effects” here—have many contributing causes.

Several systematic approaches can be used to carefully analyze and identify the many contributing causes of various effects, including system failures or other problems. Each of these tools avoids the single cause fallacy, by helping to identify the many factors contributing to each outcome. One of the simplest and most powerful is the Cause-and-Effect diagram, also known as a fishbone diagram or an Ishikawa diagram. The failure mode and effects analysis is a related tool that is more rigorous and will not be covered further in this course.

These ideas are more fully developed in the Wikiversity course Attributing Blame.

Several examples that illustrate problem finding are developed here. An outline representing a cause-effect diagram is provided for each example problem. Each cause-effect diagram includes the “presenting symptom” (e.g. “late to work”, a list of “proximate causes” (e.g. “getting up late”), a list of contributing causes, and perhaps an ultimate cause or root cause.

Considering the causes that contribute to each problem illustrated here, what cause is the best to act on to solve the problem? Where in the causal chain would intervention be most effective?

Auto Accident
Causes contributing to an auto accident are analyzed in the Cause-Effect analysis section of the Wikiversity course Attributing Blame. Please refer to that example.

Suboptimal Life Experiences
An ambitions and preliminary analysis of the many causes of “suboptimal life experiences” is being developed as a research project. Please study the on-going work, use it as an example, and contribute to the research effort if you would like to.
